On February 11, just one month after a chemical spill tainted
drinking water for 300,000 people in and around the state’s capital of
Charleston, West Virginia experienced another environmental disaster: 100,000 gallons of coal slurry pour into
stream.

From The West Virginia Gazette:
“More than 100,000 gallons of coal slurry poured into an eastern
Kanawha County stream Tuesday in what officials were calling a ‘significant
spill’ from a Patriot Coal processing facility.
Emergency officials and environmental inspectors said roughly six
miles of Fields Creek had been blackened and that a smaller amount of the
slurry made it into the Kanawha River near Chesapeake.
‘This has had significant, adverse environmental impact to Fields
Creek and an unknown amount of impact to the Kanawha River,’ said Secretary
Randy Huffman of the state Department of Environmental Protection.”
State officials in West Virginia are scrambling to contain the
coal slurry spill, which could affect the Kanawha River, just as they scrambled
to contain that toxic chemical spill last month that released the toxic
chemical 4-methylcyclohexanemethanol, or MCHM, into the Elk River, a tributary
of that same Kanawha River.
We already know about the many toxic effects of coal, and now
here’s another one: malfunctioning equipment.
The spill at Patriot Coal was apparently caused when a valve
inside a slurry line malfunctioned, carrying material from the preparation
plant to a separate disposal site, not to an impoundment, according to
officials from the state Department of Environmental Protection (DEP).
Coal slurry or sludge is a waste fluid produced by washing coal
with water and chemicals prior to shipping the coal to market. It contains a
variety of substances that are likely more toxic than heavy metals, like iron,
manganese, aluminum and selenium.
Several Unanswered Questions
Companies are required to immediately report any spills to the
DEP. However, although the valve broke sometime between 2:30 and 5:30 early on
the morning of February 11, Patriot Coal did not call the DEP to alert them of
the leak until 7:40 that morning.
In addition, even though there was an alarm system in place, the
alarm failed, so pumps continued to send the toxic slurry through the system. A
secondary containment wall around the valve proved to be insufficient; the
pumps continued to send slurry to the broken valve, which became overwhelmed
and the slurry overflowed the wall and made its way to the creek.
Officials at the company announced immediately that containment efforts and cleanup
activities were underway.
